Preheat your oven to 375 degrees and grease your muffin tin.
In a large bowl, combine your dry ingredients (flour, baking soda, baking powder, salt, lemon zest, poppy seeds) with your sugar. Mix well.
In a smaller bowl, combine wet ingredients (oil, eggs, yogurt) and mix well. Fold the wet ingredients into the larger bowl with the dry ingredients. Fill the muffin tins 3/4 way. Sprinkle with raw sugar and bake for 15-20 minutes or until a toothpick comes out clean.
Make the glaze. Whisk oat milk and powdered sugar together. Once muffins have cooled for at least 20 minutes, pour the glaze over muffins and sprinkle with poppy seeds and lemon zest. Enjoy!
